In order to emulate the behavior of something like a Kaosspad I’ve setup an XY pad and a button. By pressing the button I’m enabling the effect and then using the pad to adjust. Uses 2 fingers.
If OSCPilot sent a separate “Touched” message separate from X or Y as soon as the XY pad was touched it would eliminate the need for a second finger.
I believe TouchOSC had a feature similar to this.
